放疗计划自动独立核对软件的实现及应用

目的 设计并实现放疗计划自动独立核对软件(AutoReview),提高独立核对的工作效能。方法 通过SQL语言连接记录验证系统数据库,读取并解析该系统中患者电子治疗计划单。根据计划单提供的治疗计划信息,AutoReview分别从计划系统和记录验证系统获取与该治疗计划相关的所有参数,并以结构化的数据存入本地数据库。针对不同的核对内容,制定相应的核对逻辑,编写程序实现各检查项的自动化独立核对。选取1个月实际临床治疗计划(664例)作为样本,评估临床应用效果。结果 与人工核对相比,AutoReview将核对工作效率提高了近60倍,问题检出率提高19.2%。在2年的临床应用中,软件运行稳定,完成了14509例治疗计划的自动独立核对,其中发现问题计划588例,占比4.05%。结论 AutoReview可有效地提高独立核对的效率和准确率。

Realization and application of automatic independent check software for radiotherapy treatment plans

Objective To design and implement an automatic independent check software (AutoReview) for the radiotherapy treatment plan and improve the efficiency of independent check. Methods
The patient′s electronic treatment plan chart in the record and verify (R&V) system database accessed by the SQL language was read and parsed. Based on the treatment plan information obtained from the chart, AutoReview extracted all parameters related to the treatment plan from the treatment planning system and the R&V system, and saved the structured data into a local database. For different check items, corresponding check logic was designed and the program was written to realize the automatic independent check. In total, 664 clinical treatment plans for one month were selected as a sample to evaluate the clinical application effect. Results Compared with manual check, AutoReview improved the check efficiency by nearly 60 times and the problem detection rate was elevated by 19.2%. In the two-year clinical application, the software operation was stable, and 14509 treatment plans were automatically checked and identified 588 cases with problems, accounting for 4.05%. Conclusion AutoReview can effectively improve the efficiency and accuracy of independent check in radiotherapy treatment plan.
